Performing Response Spectrum Analysis Using Ansys Mechanical — Lesson 1

Response spectrum is a mode superposition linear analysis that uses the results of a modal analysis with a known spectrum to calculate displacements and stresses in the model. Three types of input excitation spectrum are supported: displacement, velocity, and acceleration.  The mode coefficients are calculated by the program from the modal analysis participation factors and the spectrum values, and this is used to combine the modal responses to estimate the overall peak response; there is no deformed shape nor output as a function of time or frequency. // INTERESTED IN MORE?
